Abstract
The utility model discloses a running speed reducer brake for service braking. One end of the brake and an input end of a running speed reducer are connected onto a vehicle frame by bolts, the other end of the brake and an output end of the running speed reducer are connected onto wheels, and the brake comprises cylinder covers, disc springs, retainer rings, pistons, X-shaped sealing rings, ventilating caps, cylinders, outer friction plates, inner friction plates, floating sealing seats, connectors, floating sealing rings, screw plugs and the bolts. Braking is realized by means of adjusting released pressure so as to change braking torque. The running speed reducer brake has the remarkable advantages that the running speed reducer brake is advanced in design and reliable in braking, can be connected with the running speed reducer, a frame and tires conveniently, and the like.
Description
Technical field
The utility model relates to manufacturing and the design that belongs to haulage device, the particularly technology of the design of haulage device component and manufacturing.
Background technique
The utility model is mainly used in the heavy machinery traveller, and single speed reducer bears a heavy burden in 20 tons, and the speed of travel needs the walking of service brake to drive speed reducer below 10 kilometers/hour.Usually walking drives speed reducer and generally adopts the built-in hydraulic pressure of input end, friction plate conventional brake mode, adopt the brake type speed reducer of hydraulic spring grease cup friction disk type in the design, its mode of braking is the input end braking, be that the friction catch moment of torsion is realized effectively braking greater than the oil hydraulic motor input torque, be mainly used in parking braking.When being used for service brake, because braking kinetic energy is very big, the friction plate useful area is less, can not effectively absorb braking kinetic energy; Friction plate high temperature can cause problems such as friction and hydraulic seal class material failure, friction material are subjected to displacement, and causes braking failure at last.The input end mode of braking can only be used for parking braking, can not be used for service brake.
Summary of the invention
The purpose of this utility model for overcoming above-mentioned technical deficiency, is carried out innovative design to driving speed reducer break brake structure exactly, satisfies heavy machinery traveller driving speed reducer service brake requirement.
Mode of braking in the technical solutions of the utility model is braked for walking drives the speed reducer output terminal, promptly uses outlet structure.Its main structure is made up of cylinder cap, butterfly spring, back-up ring, piston, X RunddichtringO, ventilative cap, cylinder body, outside friction disc, interior friction plate, floating sealing base, connecting body, floating seal ring, plug screw, bolt.Cylinder cap 2, cylinder body 8, floating sealing base body 11 by bolt 16 connect one and and driving speed reducer 1 input end, cylinder cap 2 cylindrical A end face C and frame pass through screw B Bolt Connection; Outside friction disc 9 is connected with cylinder body 8 by spline and limits its rotation; Cylinder body 8 is provided with break filler opening, ventilative cap 7; Connecting body 12 is provided with cold oil and annotates fuel outlet; Connecting body 12 left ends and driving speed reducer output terminal link into an integrated entity by bolt 15, and 12 cylindrical D end face F are connected with bolt by screw E with tire by connecting body; Between floating sealing base 11 and connecting body 12, adopt floating seal ring 13 sealings; Interior friction plate 10 is connected with connecting body 12 by spline, rotates with the walking speed reducer.The power of oil hydraulic motor is after planetary speed reducer slows down, and the speed reducer output terminal is connected output torque by connecting body 12 with tire.By the compress degree of piston 5 changes to friction plate, and the size of change friction torque.Just can travel by tire on the drive wheels by the transmission of retarder like this.Just can realize braking and the deceleration of heavy machinery driving speed reducer in driving process by the combination degree of hydraulic control friction brake. vehicle is freely exercised when break is thrown off fully, when break fully in conjunction with the time, just can brake fully wheel.
Described butterfly spring 3 is formed cluster spring by 6-10 sheet ring shape reed, is arranged into annular.Described outside friction disc 9 is that 11 or 13 circle lamellar bodies and interior friction plate 10 are that 10 or 12 circle sheets are formed.Described driving speed reducer break is an outlet structure.Promptly be installed in speed reducer output terminal outside.It links together with driving speed reducer, frame and tire respectively.
The utility model is compared with background technique has significant beneficial effect, is not changing the driving speed reducer structure, can be convenient to use by additional output terminal break.By increasing the friction plate useful area, overcome the deficiency of input end braking, compare with the built-in break speed reducer of identical driving torque, the friction plate useful area increases nearly 280 times, effectively absorb that the heavy machinery driving speed reducer is braked in motion and the braking kinetic energy that produces can carry out service brake effectively reliably.
The utility model is described in further detail below in conjunction with accompanying drawing.
